Bis(μ-4,4″-difluoro-1,1′:3′,1″-terphenyl- 2′-carboxylato-k2O:O′)bis[aqua(4,4″-difluoro-1, 1′:3′, 1″-terphenyl-2′-carboxylato-kO)(pyridine-kN) cobalt(II)] diethyl ether disolvate

Abstract

The structure of the title compound, [Co2(C19H 11F2O2)4-(C5H 5N)2(H2O)2]·2C 4H10O, comprises two CoII atoms in a distorted square pyramidal coordination environment, straddling a crystallographic inversion center with a Co···Co separation of 3.1923 (15) Å. Each Co2+ cation is coordinated by three O atoms of three 4,4″-difluoro-1,1′:3′,1″-terphenyl-2′-carboxylate ligands, one water O atom and one pyridine N atom, forming a CoO4N polyhedron. Strong intramolecular O-H···O hydrogen bonds are observed between terminal metal-bound carboxylate groups and water O atoms.
